Master-slave settings and other configurations
1.module master-slave mode settings:
The DX-BT05 4.0 Bluetooth module supports both the master/slave mode of the software/hardware configuration. The specific method is as follows:
27 pin - software / hardware master-slave setting port: set low (or hanging) for the hardware to set the master-slave mode, set 3.3V high for the software to set the master-slave mode; if you select the hardware settings master-slave mode, you can pass 28 feet If you choose the software to set the master-slave mode, you can query and set it by AT command.
28 pin - hardware master-slave setup port: 3.3V high level set master mode, ground or hanging set slave mode.
2.Wakeup module settings are three ways:
Method 1: You can activate the module by sending a string of about 80 characters. The activation string sent cannot contain the AT command. After successful wake-up, the serial port will output the string +WAKErnOKrn.
Method 2:Short press the system button SW1.
Method 3: Direct pairing connection.
3. System pin button (P1 or 3)
P1_3 is the input pin. Short press the control to achieve the following functions: 1. When the module is in the sleep state: The module will be awakened to the normal state. After successful wake-up, the serial port will output the “+WAKErnOK”rn string. 2. When the module is in the connected state: the module will initiate a disconnect request.
